Smarter than the average lockbox, Yeeuu’s K1 Smart Lock Box enables you to control and monitor entry access from your phone. The Airbnb-friendly system consists of a lockbox with an access-code protected lock that is activated/deactivated by the unique bluetooth signal of the user’s device. The system is flexible, allowing you customizable, programmable control and multi-person entry. The K1 is constructed of aluminum alloy and steel and is powered by a trio of AAA batteries that will keep it powered up for 1 full year.
